The quilt patch titled
     Subject: selftests/mm: fix split_huge_page_test for folio_split() tests
has been removed from the -mm tree.  Its filename was
     selftests-mm-fix-split_huge_page_test-for-folio_split-tests.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: selftests/mm: fix split_huge_page_test for folio_split() tests
Date: Tue, 8 Jul 2025 21:27:59 -0400

PID_FMT does not have an offset field, so folio_split() tests are not
performed.  Add PID_FMT_OFFSET with an offset field and use it to perform
folio_split() tests.
